I'm happiest when I'm moving.

Health is never going to go out of fashion.

I am nearly the worst role model for a healthy person. To me, a healthy person is someone in balance. Sometimes you eat hamburgers, sometimes salad; sometimes you move, sometimes you don't. I eat more healthily than unhealthily, but I do sometimes eat unhealthy food.

Children don't really understand the concept of health. You can't give them an apple and say 'if you eat this you will be healthy when you're older' because they don't understand. You have to find a different way to motivate them.

Children up to the age of seven are like sponges. They look up to adults and copy what they do. So I thought if I could create a positive role model - a superhero, if you like - who moves around and has a balanced lifestyle - then they would be motivated to move more.

I realised there were no good role models for kids. Popeye eats spinach, but also smokes and hits people.

I honestly think that kids should not exercise: they should keep fit through play. The most important age is zero to seven, both for the kid and the parent - for parents, because this is the time when your kid learns how to walk, talk and other behaviour.

If parents could just get their children moving around in the most simple and fun ways - jumping in leaves, dancing to pop music, throwing socks in a laundry basket - they could be sowing the seeds of great habits that could last a lifetime. It is all about turning it into a game.

I learned that there are two things that kids really like: movement and love. Happy kids move; unhappy, they don't move.

The biggest thing you can give a kid is self-esteem, so that they're not shy to do different things.
